If one team is leading by 35 or more points at halftime, and the two coaches agree, a running clock can be used in the entire second half.

If the two coaches do not agree, but the advantage is 35 or more points after three quarters, a running clock will be used automatically for the balance of the game.

It’s a similar rule to basketball where a 40-point lead starting the fourth quarter produces a running clock that considerably shortens the game.
